J OB D. VILKINSON, OF PLAINVELL, MICHIGAN.

SPRING BED-BOTTQM.

SPECIFICATION forming part of-Letters Patent No. 285,331, datedSeptember 18, 1883.

Application filed October 3l, 1892.

new and useful Improvements in Spring Bed- Bot-toms; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to letters or figures of reference markedthereon, which form a part of this specification.

This invention relates to certain new and useful improvements in springbed-bottoms,.

and it consists in providing twin springs with a horizontal extended topand a V-shaped bridge, which unites the springs, the same being providedwith hooks for uniting one set of the twin coils to the preceding coil.

My inventionV also consists in providing a bed-frame with hooks and eyesanda W- shaped connecting-link having hooks formed thereon, as will behereinafter more fully set forth, and pointed out in the claims.

In the annexed drawings, Figure lis a plan view of the bed-frame with myimproved bottom attached thereto. Fig. 2 is a perspective view of one ofthe springs having hooked ends. Fig. 3 is a perspective view of one ofthe connecting-links which `connects the last of the series of thesprings with the bed-frame, and Fig. et is a perspective view of one ofthe end springs. f

In the annexed drawings, A represents the bed-frame, which is providedwith longitudinal supporting-rails and removable transverse slats7 towhich the springs are secured. To the transverse foot and head boards ofthe bed frame are secured hooks c and eyes b, which are attached to theframe on the saine horizontal line as the tops of the springs. Thesprings which are secured to the transverse slats are made of a singlepiece of wire, and have their ends bent downward on a vertical line withthe conical portion. By these ends they are secured to the transverseslat-s.

The springs consist7 essentially, of two opposite coiled members, B B',the upper coils of which extend outwardly for a short distance (Nomodel.)

from the spring. From this point the wires c c converge toward eachother. They are then bent back upon the same horizontal plane toward thespring,so as to forni a V-shaped connecting portion, d. I thus forniupon a spring an upper extended supporting portion having fourhorizontal bearing-surfaces in `addition to the voluted or upperportions ofthe springs. The ends of the springs B B', with the exceptionof the last series, are bent downwardly and rearwardly to form hooks ee, by means of which the springs are united to cach other so as toforincontinuous and extended bearing-surfaces for the mattress. The outerends of these hooks c e are bent so as to be of greater length than theinner side, so as to 4Wconform to the shape ofthe adjacent coil, whichthey embrace. The springs which form the last of the series Vat one endof .the bed, to which they are secured by the hooks a, are of the sameshape as the springs hereinbefore described, but they are not providedwith hooks at their terminal portion. These springs are attached to thebed-frame A by the hooks a a. The last series of springs at the otherend of the bed are attached to the frame A by a connecting-link', asshown in Fig. 3, which link consists of a single piece of wire, which isbent so as to have parallel side portions, ff, which are connected by acentral V-shaped portion, which extends horizontally toward the terminalof the sides f f. The end portions of this link are bent downwardly, soas to forni hooks h and t'.

To make use of my invention, the springs are attached to the transverseslats so that the projecting portions will all be in the same line,

the hooks and eyes being secured to the head IOO the mattress, andVwhich may be packed for transportation in a small space.

Having thus described iny invention, what I clainl as new, and desire tosecure by Letters Patent, is-

l. Asa new article of manufacture, the twin springs made from one pieceof wire coiled in opposite directions and provided on the samehorizontal plane as the upper coils with a voluted portion which extendsoutwardly from the coils and then converges in straightlines, theuniting portion being bent toward the coils, substantially as shown anddescribed.

2. The twin springs made from a single piece of wire having conical orvoluted portion B B', with intermediate horizontal por! tions, c, c, andd, and hooks e e, substantially as described, and for the purpose setforth.

3. The connecting-link having parallel sides,

f f, and central V-shaped portion and end hooks, 7L and z',substantially as shown and for the purpose set forth.

4. In a spring bed-bottom, a series of twin `springs provided withhorizontal extending portions with end hooks, by which they are unitedto each other, in combination with the end links and hooks and eyesattached to the bed frame, substantially as described and shown.

In testimony whereof I afiix iny signature in presence of two witnesses.
